Hand over execution Variable to Activiti 'Call Activity'

[corch]

Hey there 😃

I am designing a process which calls a subprocess. In this call no variables will be handed over. But the subprocess needs the 'execution' variable to get some mor information about the process like the 'entryClassPK'. But I have no idea which could be the right variable.

The subprocess call looks like this:

  
  <callActivity id="callactivity1" name="Call activity" calledElement="forschungsantrag_ueberpruefen">
    <extensionElements>
      <activiti:in source="execution" target="execution"></activiti:in>
      <activiti:out source="execution" target="execution"></activiti:out>
    </extensionElements>
  </callActivity>

Thank you for your answer 😃

I forgot to mention that I use Liferay in which I uploaded the mentioned processes.
